Hi everybody,
I'm Brazillian and new member in the list, and i need a little help.
Scenary:
2 servers in replicated mode (server1 and server2)
1 new server - server3 - that I'll replace by server2.
Today i has just one volume (gv0) and 2 bricks - servergv01 and server2.
I want replace server2 by server3, the volume (gv0) has a 1.1T in
total used space.
The steps that i followed was:
1. gluster peer probe server3
2. gluster volume replace-brick gv0 server2:/data server3:/data start
After 2 days, the status of the migration was:
Number of files migrated = 4308293 Migration Complete
But just was copied 821G of server2:
This is the second time that it occurs, the first time just was copied
124G.
My gluster version is 3.3.1
Can anyone help to find a solutjon, i need to remove all files and
start again ?
Thanks!
Replace brick code has some issues. Hence there are plans to retire
replace brick for cases where data migration is required (there was a
discussion in gluster-devel about it). However we can use add brick and
remove brick in a way which will work as a replacement for
replace-brick. Below are the steps.
* Add new brick
# gluster volume add-brick <VOLNAME> [<replica>
<COUNT>] <NEW-BRICK> ...
* *Do not**run rebalance*
* Remove old brick
#gluster volume remove-brick <VOLNAME> [replica <COUNT>]
<BRICK> ... start
* #gluster volume remove-brick <VOLNAME> [replica <COUNT>] <BRICK> ...
status
* Once status shows all completed,
* #gluster volume remove-brick <VOLNAME> [replica <COUNT>] <BRICK> ...
commit
Thanks,
Lala
